ableothers'skilled in the art to makeand use the same, reference beinghad to the accompanying drawing.

' forming part of this specification.

This invention relates to an improved buffing device for finishingspoons, and consists in the application to the large boning-wheel's nowcommonly used,

' and arranged for attachment to the spindle of a lathe,

o'i'a short spindle, on which is mounted, a little distance from theside oi' the said large wheel, a smallbufiing-wheel, adapted forpolishing the inner surface of the bowl of the spoon, the said wheelbeing detachably connected to the spindle, so that others of dili'en'ent sizes may be attached. 1 The drawing representsa sectional elevationof my improved 'bnfling device, and a part of the lathe, showing themanner of support and operating it, the latter 7 being shown in dottedlines.

A is the large buffing" or polishing-wheelcommonly used. It is providedwith ametallic screw-threaded cone, arranged for the attachment to alathe-spindle or mandrel by screwing thereon.

These large wheels will not'work in the concave sides of the bowls,owing to their size; consequently it has been the practice, up to thepresent time, to finish them by hand.

I for the concavities and the plane parts also.

, The Schedt fle referred to in these Lettem'Pateul: and making part ofthe same I, therefore, propose to attach a short spindle, B, to the coneof the wheel A, by screwinginto the axial screw-threaded hole thereof,or by other means of at tachment, and mount on the said spindle, asuitable distancefi'om the said wheel A, a small butfing-wheel,

G, which will work in the concavity of the spoon, and

polish the surfitce-thereof equally as well, and nearly as rapidly, asthe other parts are done by the large wheel.

' It is necessary to make the wheel A, forpolishing the plane parts,large, to have the necessary degree of endurance otherwise one smallwheel might answer I have therefor provided on the one attachment forthe teeth,

and the two wheels A U, suited, in every respect, for

polishing the spoon in all parts.

Having thus described my invention,

. '1 claim as new and desire to secure by Letters Patent A buffingorpolishing attachment for lathes,-eonsisting of tl'ielarge butfing\vheelA, the spindle B, and the small wheel G, all constructed and arrangedsubstantially as specified.

The above specification of my invention signed by me this 1st day ofMarch, 1870.
